Composition of the Aluminum Table of Elements
The aluminum table of elements is composed of 13 protons, 14 neutrons, and 13 electrons. This configuration gives aluminum its unique chemical properties and reactivity. The atomic mass of aluminum is 26.98 u (unified atomic mass units), which is relatively low compared to other metals.
Aluminum's electron configuration is [Ne] 3s² 3p¹, indicating that it has a full outer energy level and only one electron in the p-orbital. This configuration makes aluminum a relatively soft and malleable metal, with a high capacity for oxidation.
The isotopes of aluminum include ²⁶Al, ²⁷Al, and ²⁸Al, with ²⁶Al being the most abundant. The half-life of ²⁶Al is approximately 717,000 years, making it a useful tool for dating archaeological samples.
Properties of the Aluminum Table of Elements
Aluminum's physical properties make it an attractive material for a wide range of applications. It has a melting point of 660.32°C and a boiling point of 2470°C. Aluminum is also highly malleable and ductile, making it easy to shape and form into various products.
